RE: debug java program on AS400(debug tomcat)

I have an update...
With Tomcat starting on port 8080 (as per server.xml)
and jpda set to port 8000 (as per catalina.sh), I am
able to define my remote connection in Eclipse to port
 8000 and it does seem to connect. (please note that
when both are set to the same value, I cannot connect
from Eclipse)

Then I open my IE Browser and hit my app running on
port 8080 of the as400 as follows:
  http://myHost:8080/MyApp/form/login.jsp

My app successfully loads to the page. However, I have
breakpoints setup in Eclipse and I expected the app to
hook into the IDE when I hit the breakpoints so that I
can debug, but it does not do this. So in short, it
appears that I am connecting to the JVM but not
hooking/debugging into the app.

Any ideas?

Thanks,
Ivan
